In other words, a messenger-linked service may enable a large amount of data to be transmitted and shared through the messenger 110.

A social graph illustrates interconnections among people, groups and organizations in a social network. The term refers to both the social network itself and a diagram representing the network. Individuals and organizations, called actors or friends, are nodes on the graph. Inter-dependencies, called ties or relationships, can be multiple and diverse, including such characteristics or concepts as age, gender, race, genealogy, chain of command, ideas, financial transactions, trade relationships, political affiliations, club memberships, occupation, education, economic status, human relationships, friend relationships and social relationships. A social graph of a particular user consists of the set of nodes and ties connected, directly or indirectly, to that actor.

FIG. 2 illustrates a messenger-linked service system 200 according to exemplary embodiments. The messenger-linked service system 200 may use a social graph based on a human relationship of a messenger platform, and may perform user authentication between a messenger and a messenger-linked application.

The messenger-linked service system 200 of FIG. 2 may include a relationship extraction unit 210, a selection unit 220, and an execution unit 230. The relationship extraction unit 210 may extract a social graph between a user of a messenger and a friend. The selection unit 220 may select data that is either transmitted to or shared with the friend in the messenger-linked application. The execution unit 230 may transmit the selected data to the friend, or may execute a sharing request.

The user authentication in the messenger-linked service system 200 may be automatically processed by obtaining a user's consent. The user consent may be obtained when user authentication is completed in the messenger. A messenger-linked service system may service a user's consent.

The relationship extraction unit 210 may extract a social graph of a friend relationship, and a social graph of a group relationship, a chat history of the group relationship and a chat history of the friend relationship. Accordingly, a potential target to which the user transmits data or sends a sharing request may be a group, a friend, or a chat room, without any limitation to a friend list of the user.

The selection unit 220 may select the messenger-linked application, or data associated with the messenger-linked application. The data associated with the messenger-linked application may be transmitted to a friend or shared with the friend. The data associated with the messenger-linked application may be extracted from data stored in the messenger-linked application, or may be written as new data associated with the messenger-linked application. The selected data or the selected messenger-linked application may be transmitted to a target extracted by the relationship extraction unit 210, or may be requested to be shared.

The execution unit 230 may be linked to a messenger-linked service and may be invoked during execution of the messenger-linked application. The execution unit 230 may call a social graph or a chat history of each of a friend relationship and a group relationship. The execution unit 230 may select a friend, a group or a chat history to which data is to be transmitted or shared, and transmit data or execute a sharing request. In this instance, there is no limitation to a number of selected targets or a type of targets.

The messenger-linked service system 200 may transfer information regarding data transmission and execution of the sharing request through a push alert, a notification alert, or a chat message based on a setting of the user.

Examples of use of a messenger-linked service will be described with reference to FIGS. 3 through 5. FIG. 3 illustrates a sender transmitting data using a messenger-linked service. FIGS. 4 and 5 illustrate a receiver receiving data from a sender. In accordance with an illustrative example, the term “sender” may be used interchangeably with a “user.”

The sender may determine how the receiver receives an alert. The sender may select an alert from among a push alert, a notification alert, or an alert via a chat room, and may enable the receiver to receive the selected alert.

Referring to FIG. 3, a user may write new data and transmit the new data using a messenger schedule application. The new data may be used to vote for or against available schedules and locations of an event that the user desires to share. For example, as shown in FIG. 3, when the user taps on a screen to add a member to whom a sharing request is to be sent a next screen may appear. A friend list of FIG. 3 may be a friend list of friends based on a messenger platform, and a target may be selected from among a friend tab, a group tab and a chat tab. For example, a list of groups or meetings to which the sender belongs may be selected from the group tab; and either a chat room shared between or in common with the sender and a friend or a chat room of each group may be selected from the chat tab. However, there is no limitation to the selected target and a number of selected targets. When selection of the target is completed, data or a sharing request may be automatically transmitted to the receiver. In another exemplary embodiment, data or a sharing request may be transmitted to the receiver after selection of the target is completed and confirmation to transmit is received.

In FIGS. 3 and 5, a schedule for “Company meeting in October” may be requested to be shared, and a vote on the schedule may be performed. Additionally, “Group 1” may be used as a target for the vote.

When the sender transmits a request, a system may perform an alert that is selected in advance by the sender, so that a receiver may instantly verify the request. As shown in FIGS. 4 and 5, the receiver may receive data from the sender of FIG. 3 and check the received data, and the sender may send a request to share a vote on a schedule and location of “Company meeting in October.” In an example, when the sender selects, in advance, the alert via the chat room, the receiver may: check information sent by the user via a chat room of a messenger, tap information received via the chat room, and participate in the vote, as illustrated in FIG. 4.

In another example, when the sender selects the push alert or the notification alert of FIG. 3 and sends the request, an alert window may appear on top of an idle screen of the receiver, as shown in FIG. 5. Additionally, when a button “details” of FIG. 5 is tapped, the receiver may check information sent by the user and may participate in the vote.

According to exemplary embodiments, a messenger-linked service system may use a social graph based on a human relationship of a messenger platform. The messenger-linked service system may be operated by executing a messenger-linked application. The messenger-linked service system may include a selection unit, a relationship extraction unit, and an execution unit. The selection unit may select data that is to be transmitted to a friend or shared with the friend in the messenger-linked application. The relationship extraction unit may extract a social graph between a user of a messenger and the friend. The execution unit may transmit the selected data to the friend, or may execute a sharing request.

A messenger-linked service system may perform a messenger-linked service using a method in which user authentication is not performed.

The messenger-linked service system may be performed by linking a human relationship of a messenger platform to a messenger-linked application. When a messenger is operated, a social graph or a chat history of each of a friend relationship and a group relationship may be automatically called. In some embodiments, the term automatically can be defined as “without data entry by a user.” An alert via a chat room may be selected and transmitted to a chat room of the messenger. A push alert or a notification alert may be selected. A chat history or a target to be shared may be selected. Selected data may be transmitted or a sharing request may be executed.

Examples associated with the messenger-linked service system will be described with reference to FIGS. 6 through 8. As described above, a messenger-linked service may be performed by executing the messenger-linked application.

FIG. 6 illustrates a screen of a sender using a messenger-linked service with a card application. The messenger-linked service may be performed by executing a messenger-linked application. The sender writes a card by executing the card application, and may determine a receiver of the card using the messenger-linked service. The sender may operate a messenger without user authentication, and may automatically call a social graph or a chat history of each of a group relationship and a friend relationship. In some embodiments, the term automatically can be defined as “without data entry by a user.” Similar to the example of FIG. 3, a target may be selected from among a friend tab, a group tab, and a chat tab. For example, a list of groups or meetings to which the sender belongs may be selected from the group tab, and a chat room between the sender and a friend, or a chat room of each group may be selected from the chat tab.

FIGS. 7 and 8 illustrate a receiver checking a card received from a sender via a messenger-linked service. When the messenger-linked service is performed, information regarding data transmission and execution of a sharing request may be transferred through a push alert, a notification alert, or a chat message based on a setting of the sender. When a written card is transferred to the receiver through a chat message, a card alert may be displayed as a chat window on a chat room of a messenger, as shown in FIG. 7, so that the receiver may check the card. In another example, as shown in FIG. 8, when the card is transferred from the sender to the receiver through the push alert and the notification alert, an alert window may appear on a top of an idle screen of the receiver. In this example, the receiver may tap on “details” of the alert window, and may check the card without a need to execute a messenger.

FIG. 9 illustrates a messenger-linked service method according to exemplary embodiments. The messenger-linked service method may use a social graph based on a human relationship of a messenger platform. The method may be performed by performing user authentication between a messenger and a messenger-linked application. Operations of the messenger-linked service method of FIG. 9 may be performed based on the messenger-linked service system 200 of FIG. 2.

The messenger-linked service system 200 may perform a step 910 of extracting a social graph between a user of a messenger and a friend, a step 920 of selecting data that is to be transmitted to the friend or shared with the friend in the messenger-linked application, and a step 930 of transmitting the selected data to the friend or executing a sharing request.

In the messenger-linked service method of FIG. 9, the user authentication may be automatically processed by obtaining a user's consent when the messenger-linked application is used. The messenger-linked service method of FIG. 9 may be performed with respect to an authenticated user.

In step 910, the messenger-linked service system 200 may extract a social graph of a group relationship of the messenger, a social graph of a friend relationship of the messenger, a chat history of the group relationship and a chat history of the friend relationship. The extracted social graphs and chat histories may be transmitted, and requested to be shared.

In step 920, the messenger-linked service system 200 may select the messenger-linked application or data associated with the messenger-linked application. The data associated with the messenger-linked application may be transmitted to a friend or shared with the friend. The data associated with the messenger-linked application may either be extracted from data stored in the messenger-linked application or may be written as new data associated with the messenger-linked application. For example, in step 920 a camera, a schedule, a game, a photo album, a calendar, an SNS, or contacts may be selected. In some embodiments, data associated with a messenger-linked application, such as, a card application, a camera application, a schedule application, a game application, a photo album application, a calendar application, an SNS application, or a contact application, may be selected.

In step 930, the messenger-linked service system 200 may be linked to a messenger-linked service and executed within the messenger-linked application. Additionally, a social graph or a chat history of each of a friend relationship and a group relationship may be called from the messenger-linked application, a friend or a group to which data is to be transmitted or shared, or a chat history may be selected, and the data selected in step 920 may be transmitted or the sharing request may be executed.

In the messenger-linked service method of FIG. 9, the selected data may be transferred through a push alert, a notification alert, or a chat message, based on a setting of the user.

FIG. 10 illustrates a messenger-linked service method according to exemplary embodiments. The messenger-linked service method of FIG. 10 may be provided to a user who does not pass through user authentication. Operations of the messenger-linked service method of FIG. 10 may be performed based on the messenger-linked service system 200 of FIG. 2.

The messenger-linked service method of FIG. 10 may be performed by executing a messenger-linked application, and may use a social graph based on a human relationship of a messenger platform. The messenger-linked service method of FIG. 10 may include a step 1010 of selecting data that is to be transmitted to a friend or shared with the friend in the messenger-linked application, a step 1020 of extracting a social graph between a user of a messenger and the friend, and a step 1030 of transmitting the selected data to the friend or executing a sharing request.

In step 1020, the human relationship of the messenger platform may be linked to the messenger-linked application, and may be extracted.

When the messenger is operated, a social graph or a chat history of each of a friend relationship and a group relationship may be automatically called, and a target including a chat history may be selected for transmission or sharing through the messenger. Subsequently, the selected data may be transmitted or the sharing request may be executed. The messenger may use the messenger-linked service and may be executed to call a target to which data is to be transmitted, or a target to which a sharing request is to be sent.

According to embodiments of the present invention, data of an application linked to a messenger may be transmitted or shared through a friend, a group, or a chat room in the messenger, and thus it is possible to provide a more convenient linked service, and to diversify a type of the data.

According to embodiments of the present invention, it is possible to link a messenger to a messenger-linked application, without a need to individually recommend friends or groups in the messenger and to solve conventional inconveniences.

A computer system may be used as a computer-readable medium that includes an instruction to control a messenger-linked service method using a social graph based on a human relationship of a messenger platform to be performed by performing user authentication between a messenger and a messenger-linked application.
